I'm not confident that the average person is aware of an em dash nor that it is widely associated with AI; I think the current culturally dominant meaning is just a fat hyphen (which most people just call a dash anyway).
My wife was working from home recently and I overheard a meeting she was having. It's a very non technical field. She and her team were working on a presentation and her boss said "let's use one of those little AI dashes here."
